GONG-BELL.

SPECIFICATION forming part of Letters Patent No. 252,177, dated January 10, 1882. Application filed October 31, 1881. (ModeL) To all whom it may concern:

Be it known that I, FREDRIGK W. BRocK- SIEPEB, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Gong-Bells; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure 1, a front view, the bell removed, showing the base-plate mechanism; Fig. 2 a portion of the same, illustrating the operation.

This invention relates to an improvement in that classof gong-bells which are placed directly upon the inside of a door to be operated bya lever upon the outside, or, placed at a distance, may be operated by a connected wire-pull, the object of the invention being a simple construction to avoid the hinged latch necessary in the usual construction; and it consists in the construction as hereinafter described, and more particularly recited in the claim. 1

A represents the base or plate, which is fitted with ears B for attachment or otherwise, and with the usual center-post, C, to which the hell is secured in the usual manner.

D is the slide, arranged to move in a plane parallel with the plane of the plate A, one end, a, working through the flange on the plate so as to be guided in its longitudinal movement,

and at that end is provided with a perforation to which the wire may be attached, and is also constructed with a slot, b, in which the arm ol' a lever may work to move the slide. Either or both these devices may be embodied in the slide, or other devices may be applied to 0p crate the slide. At the opposite end the slide is constructed with an opening, d, which lies over a stud, e, smaller than the opening d that is to say, the opening at is of suflicient length to allow the longitudinal movement of the slide, and also wide enough to allow a certain amount of'latcral movement to that end. E is the hammer-lever, hung upon a pivot,f, on the plate A, provided at its other end with the hammer F in the usual manner, and so as to turn upon the pivot fin a plane parallel with the plate A. On the side of the lever next the pivot is a projection, h, which bears against a corresponding projection, i, on the I slide D when the parts are in their normal condition, as seen in Fig. 1. A two-armed spring is arranged upon a stud, m, one arm, a, bearing upon the hammer-lever, as at r, so as to force the hammer outward or forward. The other arm, 8, bears against a stud or shoulder, t, on the slide D, tending to force the slide also forward toward the hammer, but the said spring yielding for the movement of the parts. When the slide is drawn outward or downward, as indicated in broken lines, Fig. 1, the projection i on the slide engages a corresponding projection, h, on the hammer, and correspondingly turns the hammer upon its pivot. If the slide moved directly downward, holding the two projections i h in contact, there would be no release of the hammer, ex-

cept when the pull was removed to disconnect the hammer from the slide. I construct the hammer-lever with a finger, a, forward of the projection h and toward the slide, and which, as the hammer-lever turns, acts as a cam against the edge of the slide D to move it laterall y, as seen in Fig. 2, until the projection 13 escapes from the projection h. Then the hammer is free to be operated by its spring and give the required blow. When the pull is released the spring acts upon the slide to force it forward, moving laterally with the projection i over the projection h, so that one comes in front of the other, as seen in Fig. 1. This lateral movement of the slide D is permitted because the opening d through the slide is larger than the stud 6, upon which it works. The action of the spring tends to press the bearing end of the slide toward the hammer, but permits lateral movement.

I claim- 7 The combination of the slide D, arranged for longitudinal movement in a plane parallel with the plate, and also forlateral movement in the same plane with the hammer-lever, the said slide constructed with a projection, i, to engage the corresponding projection, h, on the hammer-lever, the said hammer-lever constructed with a finger, u, to operate as a cam to impart a lateral movement to the slide, and a spring operating to force the parts into their place of rest, substantially as described.
